Question: In a race of 1000m, A can beat B by 100m. In a 400m, B beats C by 40m. In a race of 500m. A will beat C by-

Solution:
While A covers 1000 B covers 900
while A covers 500 B covers 450m

While B covers 400, C covers 360m
While B covers 450, C covers (360 × 450)/400 = 405m

∴ in a 500m race A will beat C by = (500 - 405) = 95m
